Replacing factory speakers (noob)

[Alien Mantis]

I installed some Pioneer coax 6.5" speakers in the front and rear positions of my Yaris 3-door hatch.

Running them off the deck power. Maybe 15 watts RMS per channel.
They sound very nice, but they put out LESS bass than the factory crap speakers did.
Doesn't matter, because I use a Hi-Pass filter on them, and I have a subwoofer for the low freq's.

If you are running coax speakers off deck power, look for the most efficient one's you can find.
The more efficient, the louder and cleaner they will sound.
My coax speakers have a 94db sensitivity rating, so they work well with low power.

A 6.5" coax speaker is only good for hi's and mid's. Don't even try to make them play bass. That is not what they are designed for.
Bass signals will only serve to distort their output.

You need bass? Get a sub(s) and amp.
